I frequently run transient simulations on very large models (>1,000,000 nodes). I find that, depending on the precise size of the mesh, there appears to be a maximum number of time steps allowed in a single transient simulation. If I exceed this maximum, any time steps after that maximum will show the entire assembly at -273.15C (absolute zero). The simulations do finish and each time step takes roughly the same amount of time to complete as the previous, only that after a certain time step, none of the temperatures make sense. Has anyone else experienced this issue? If so, have you figured out precisely what the limitation is so that I may plan my simulations accordingly?
I have 300GB of disk space and 43GB of RAM and do not appear at any time to be close to running out of either.
I have Solidworks 2014, SP 4, though the issue has occurred for me on every version of SW since at least 2012.
